Title: Package for semiconductor device
Inventor: YOKOYAMA HITOSHI
IPC: H01L23/10
Filed: 1986-05-07
Abstract: PURPOSE:To prevent poor sealing, by chamfering the outer surface of a cap part or a base part on the side of one or both sealing parts. CONSTITUTION:The outer surface of a base part 2a on the side of a sealing part is chamfered. A cap part 4 is sealed with low-melting point glass 5a. The low-melting-point glass 5a spreads along the chamfered part. Therefore, even if the same amount of the low-melting-point glass as in the case the chamfering is not performed is used, the low-melting-point glass 5a does not protrude to the outside of a package. The bonding area between the low-melting- point glass 5a and the base part 2a is larger than the area, where the chamfering is not performed. Thus the sealing strength is rather improved.
